Application filed February 7, 1924. Serial no. 691,293.

To allwhom it may concern:

Be it known that T, GEBHARD JAnenn, a citizen of the United States,residing at Columbus, in the county of Franklin and 6 State of Ohio,have invented a certain new l a single opening for the feed anddischarge of the component materials usually has such vessel mounted ina frame with a skid or more commonly upon a wheeled truck to facilitateits movement from job to job.

Such a mixer is usually provided with a loader bucket for feeding thematerials to the mixing vessel pivoted to the frame of the machine andsuitable power mechanism for raising it to mixing vessel-feedingposition 29 and then lowering it to the ground for the reception ofafresh supply. As it is important that the loader bucket shall lie asclosely to the mixer as practicable and 'as it must be raised to arelatively high point to deliver the materials to the mixing vessel itis a desideratum thata long radius of swing of the bucket to mixerfeeding position be avoided.

Several varieties of means have been proposed and illustrated in patentsfor accomplishing these results and the object of the present inventionis to provide improved and simplified means to the same ends.

The present invention is embodied in th construction herein shown anddescribed the features of novelty being finally claimed.

in the accompanying drawings- Fig. 1 is a view in side elevationillustrating a mixing vessel or drum and loader 4 equipped with myinvention showing the loader on the ground with some operating partsomitted for the sake of clearness of illustration.

Fig. 2 is a similar view showing the loader raised to position todischarge its contents into the mixing drum.

' Fig. 3 is a View in elevation looking at the left hand side of Fig. 1with the loader vessel removed.

Fig. 4; is a view like-Fig. 1 showing a modification.

In the views 5 designates the mlxmg was i sel which is mounted upon acenter spindle in a swinging yoke 6 journaled in bearings in a suitableframe 7. Such a mixing drum is usually turned on its arms by means of ofwhich are hingedat 9 to a link frame 10 that in turn is hinged at 11 tothe main frame 7 or suitable ears 12 projecting therefrom. The frame 10constitutes a pendent swinging link connecting the loader bucket Theloader bucket is to the main frame. also equipped with a cable or cables13 for raising and lowering it, said cables winding on a drum or drums1t fixed on a shaft 15 journaled in the upper end of the main frame. Theshaft 15 is driven by a sprocket chain 16 traveling around a sprocketwheel on the end of the shaft, said cable being driven by an engine (notshown) but well understood and as in common use.

The .main frame is provided with a suitable stop at 17 to limit theleftward oscillation of the link frame 10 and to afford a purchase forthe weight of the bucket in its initial swing upward. This stopis'advantageously located at a point somewhat to'the left of thevertical line from the hinging point 11 because it permits the groundposi vtion of the loader bucket to be that much fitldStjED i nearer themain frame when it is deposited on the ground.

If it be desired that the loader bucket when lowered shall rest upon aplane 18 below the plane of the bottoms of the truck wheels a link frame10 with longer side bars can be substituted for the corresponding partsshown in Figs. 1, 2 and 3 and as illustrated in Fig. 4 where the bucketis.

sions 8 abut against the upper portion of the link frame after which thebucket turns on the axis 11 to discharging position as indicated in Fig.2.

The forms of the parts can be changed without departin 'from the gist ofthe in vention as claimed.

What I claim is:

-1. The combination with a mixing vessel and a frame for supporting thesame, of a loader bucket for the mixing vessel, means for pivoting saidbucket with reference to the rame consisting of a pendently hinged link,said link having a hinged connection at its free end with the loaderbucket, and means for raising the bucket first on the lower axis andthenon the other to mixing vessel charging position.

2. The combination with a mixing vessel and a frame for supporting thesame, of a loader bucket for the mixing vessel, means ivoting saidbucket with reference to link to oscillate from one side of a verticalline from its hinging axis to the other, said link having a hingedconnection at its free end with the loader bucket, and means for raisingthe bucket first on the lower axis and then on the other to mixingvessel charging position.

3. The combination with a mixing vessel and a frame for supporting thesame, of a loader bucket for the mixing vessel, means for pivoting saidbucket with reference to the rame consisting of a pendently hinged link,said link havmg a hinged connection at its free end with the loaderbucket, and means for raising the bucket first on the lower axis andthen on the other to mixing vessel charging position and a stop forlimiting the swing of said linkvat its innermost position. v I

4. The combination with a mixing vessel and aframe for supporting thesame, of a loader bucket for the mixing ,vessel, means for ivoting saidbucket with reference to the ame consistin of a pendently hinged link,said link having a hinged connection at its free end with the loaderbucket, means for raising the bucket first on the lower axis and then onthe other to mixing vessel charging position, and a spring acting onsaid bucket tending to draw it from said charging position.
